those belrts are SIGNED by Duran not won by duran the actual belts are only about a couple grand value if it has been won inthe ring by a certain fighter that makes the value
the newer Lonsdale Belts of the last 30 , 40 years or so aren't worth ****, it depends on who held it though too improve the value. One sold a few years ago on Ebay for about 5K, so it is defo over priced, older ones no, but newer ones aren't worth it. I informed a serious collector of the one a few years ago and he wasn't even interested at all, just watch & see what it goes for! I think this is the same Belt btw!
Had confirmation that it is Clintons belt, as I've just been in contact with his daughter. It's all legit and all proceeds from the sale of the belt are going towards a new boxing gym in SE London.
If that's the case he needs to have a word with whoever's auctioning it for him. It looks dodgy and that is probably putting off a lot of potential buyers.
With the type of things he's selling, you'd think he found it in a box of stuff from a car boot sale.
